- We have a 3-level netinfo network with about four midlevel application
- servers and 60 machines. Most user definitions and home mounts are at
- the top level. I thought I'd be least disrup.tive to upgrade to 3.0
- from the bottom up. Upgrading a couple of lowest level machines
- worked fine. But when I upgraded a midlevel host (in place, not
- from a clean disk), access problems occur. Users with homes in
- the midlevel's domain still work ok, but users with homes elsewhere
- cannot access their homes. They can login, but get a blank screen.
- Root can see the list of homes on a remote file system, but can't go
- further down as it could before.
-
- Here's a representative fstab entry from the top level:
- mugcnx1:/Users /Net nfs rw,net,timeo=14,intr,noquota 0 0
-
- Here's the 2.0 exports line:
- /Users -access=allmunx,root=mugcnx1:mugcnx2:muebnx1: ...etc..
-
- mugcnx1 is the 2.0 toplevel, muebnx1 is the 3.0 midlevel.
-
- Another irritating thing. In using UserManager.app from the 3.0 midlevel
- host to a 2.1 toplevel netinfo passwd server, the app locks. "ps" shows
- it is trying to readUserLanguage. 3.0 netinfo data for user adds an
- "info" directory, and it looks like UserMangler is trying to access a
- dwrite for System Language--somewhere.
-
- I guess I'll go ahead and upgrade the toplevel server, and hope that
- this will solve the problems. I hope this is not some idiot little
- item this idiot has overlooked, or that somewhere it says "upgrade
- networks from the top down". For the curious, I can provide nidump &
- nilist output. If anybody has insight,reply direct, I'll summarize.
- If anybody is contemplating a similar upgrade, well, stay tuned.
